I l,'U'NiTED,STATES PATENT OFFICE "IRVING I. STONE, or CHICAGO, rumors Original 1%. 1',ecs,997,*aatea- This invention relates to'adevice forv supporting and centering the end of aweb roll in position :torfeed the web to a newspaper printing press. i

of the invention are to provide means for supporting 'eachend of the web rolljfrom a pair of centers in a I. firm manner so' that theweb ean-.:be taken fromthe rollin the usual way and] when ex- 1 '10 hausted the roll can be removed expeditiously bya very simple movement ofthe supportlng spindle and the mounting of the "roll will be correspondingly facilitated. The invention also involves means; for eliminating all fer- 16 rules within the spools and reducing friction when desirable; 3 1 I a Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying hich:

Figure 1 is a side view of a reel provided with a preferred embodiment of this invention showing. it in operativeposition; d f

Fig. 2 is a fragmentary view of one en @1 the reel showing the way of dismounting the spool of the exhausted roll; and

Fig. 3 is an end view of the reel.

This invention isintended to be used with the reel. comprising a shaft 10 and spiders 30 11 for supporting a plurality of web rolls R in a paper feeding device for a newspaper printing press. The spiders are formed with whatever number of arms is required to suport the desired number of rolls around the a 5 shaft 10. It will be understood that the shaft 10 is turned from, time totirne to bring a new roll up to web delivering position and to permit the core or spool of the old roll to be removed at another point. as is usual in this art.

Each of the arms of the spider at one end I of the reel is provided with a non-reciprocable steel spindle 12 fixed to each arm by a split collar 13.

spindles 16 provided with conical centers 17 This spindle has a convex, andpreferably conical, center 14 for receiving the cnn'rnnme CHUCK non WEB noLLs Serial No. 186,131.

corresponding with the centers 14 previously described. Each ofthese latter spindles is provided with a rack 18 or the like with which meshes a gear or pinion 19 on a shaft 20 carried on a bracket21 fixed to the arm 11. Theshaft is provided with a handle 22 which can be swung from the full to the dotted line position in Fig. 1 for thepurpose of reciprocating this-spindle to hold or release the web roll. It'will be understood, of course, that in the form shownthereare three pairs ofspindles arranged for the support of three Web rolls around theshaft 10, al-

' though any other convenient number can be employed. a

For the purpose of supporting the roll R on the conical centers 14 and 17 I provide a pair of chucks 25 Each of thesegis made with a solid cylindrical'shank which for an ordinary sized web roll can be about eight inclies long. The shank isbeveledoff at'the inner. end and; is intended .to be inserted in the ends of the spools 26 on" hich the roll is ound. As illustrated in the drawing,

these spools 26 may be ofextremely light construction, it being usual, in practice, to wind spirallyv and to glue, together, two thicknesses of ordinary light cardboard, whereby the manufacturing costthereof is so small that the spools -may be discarded or destroyed after a single use thus eliminating the cartage and other cost of handling the spools of the prior art which latter must be returned to the paper plants for further use, Moreover, the

cos't'of,producing the spools of the prior art are-comparatively; excessive, being of a substantially heavy construction and being pro} vided'with ferrules. Each chuck is also provided with a cylindrical or other shaped flat fiange27 which is of the web roll; thatis, the edges of the paper. In the flange is a conical central depression 28 beveled to fit the conical centers 14 and'17. These chucks are made of solid pieces of metal or even wood, if so desired, and are placed'in the ends of the spools of therolls R before they are applied to the reel. The shanks are made to fit tightly in the ends of the-spools. v

In the application ofthe rolls, one end is drawn up against the end lifted and located so that the center 14 enters the depression 28 in one of the chucks located in the roll. The other end of the roll is raised into substantially level position and then the handle 22 is moved over to push the spindle 16 toward the roll until the center 17 enters the depression 28 in the other chuck. On account of the construction shown, a forward movement of this spindle of only 2 inches is required in an ordinary newspaper printing press. To remove the spool ofthe exhaust-ed roll the spindle 16 is drawn back by means of the rack and lever. the roll and it can be removed very readily as can be seen. In this way the roll is very quickly applied and detached and no ferrules are required inside the spools.- This results in economy in use.

As these so-called chucks have cylindrical shanks of substantial length which enter the spool on which the roll is wound, they support the roll firmly at each e d and revent its getting out of centeralthough they do not extend through the roll and are not connected in any way with each other except by the spool they constitute a firm and rigid support. In unwinding of the web; they of course rotate with it on the centers 14 and'17.

Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications canbe made therein by any person skilled in the .conical center This releases in which they fit tightly. Thus,

can be rotated with the web roll in the unwinding thereof.

4. In a web roll support, the combination of a reel having pairs of arms rotatable therewith, a stationary conical center mounted on each arm at one end of the reel, a reciprocable mounted on each arm at the other end of the reel, said centers being in axialalignment. means for reciprocating the movable centers independently of each other, a pair of chucks for directly supporting each web roll, each chuck having a depression in the end for receiving the two centers and each having a material portion of a cylindrical form extending into the end of the web roll for supporting the web roll at its ends and carrying it on said centers and means limiting the extent to which the chuck will extend within the roll.

5. As an article for rigidly supporting the end of a web roll for a newspaper printing press comprising a shank portion for entering a spool of said web roll and in engagement with a supporting portion, one of said portions having a central depression for receiving a pointed end of the other of said portions and means for limiting the extent to which said chuck will extend within the spool.

2. As an article of manufacture, a chuck for rigidly supporting the end of a web roll for a newspaper printing press comprising a cylindrical shank of material length adapted to enter the spool of the web roll and fit tightly therein and having a flange on the end fitting against the end of the web roll and provided with a central conical depression for receiving a conical supporting center.

3. A supporting means for a web roll comprising a pair of chucks each having a cylin drical. shank of substantial length adapted to be fitted into the end of the spool on which the web roll is wound, each having a flange at the end engaging the end of the web roll, and each being provided with a central depression on the outer end for receiving a supporting center on which the two chucks of manufacture, a chuck I have subscribed v ios I vI30
